Description
Part of the Sentron ED frame family, this 30A MCCB delivers reliable overcurrent protection for industrial and marine applications. It features a thermal-magnetic trip unit with fixed long-time and instantaneous functions. Designed for bolt-on installation, the breaker mounts into Siemens Sentron panelboards and switchboards. It can be replaced by the 3VA51 series using a retrofit kit. The unit carries a marine-duty rating with 50°C calibration and provides 65kAIC at 480VAC.Specifications

Product FAQs
8 answersWhat does the M in the HHED63M030 catalog number signify?
The M indicates the breaker is calibrated for a 50 degrees Celsius ambient temperature. This is typically required for marine applications and high-temperature industrial environments, whereas standard ED frame breakers are calibrated for 40 degrees Celsius.
How does the HHED rating differ from standard ED frame breakers?
The HHED prefix designates an extra-high interrupting capacity. While standard ED breakers have lower fault ratings, this model provides 65kAIC at 480VAC and 100kAIC at 240VAC, making it suitable for systems with high available fault currents.
Can the HHED63M030 be used in direct current (DC) systems?
Yes, this thermal-magnetic breaker is rated for up to 250VDC with an interrupting capacity of 30kAIC. It can be applied in DC control circuits and industrial DC power distribution.
What panelboards are compatible with this bolt-on breaker?
The HHED63M030 is designed for Siemens Sentron panelboards and switchboards that accept bolt-on ED frame circuit breakers.
What wire sizes are accepted by the factory lugs?
The standard mechanical lugs on this breaker accept 10 AWG to 1/0 AWG conductors. The lugs are dual-rated for both copper (Cu) and aluminum (Al) wire.
Does this breaker support internal accessories like shunt trips?
Yes, Siemens Sentron ED frame breakers feature internal pockets that accept field-installable accessories, including shunt trips, auxiliary switches, and bell alarms.
What is the physical frame size of this breaker?
It belongs to the Siemens ED frame family. It shares the same physical footprint, mounting hardware, and accessory compatibility as other ED, HED, and CED frame breakers.
What safety steps are required before bolting this breaker to the bus?
Always de-energize and lock out the panelboard before installation. Verify the power is completely off using a properly rated voltage meter, and ensure the breaker handle is in the OFF position before making any mechanical or electrical connections.
